Access control is really a system enabling authorities to manage usage of areas and resources in a very given physical facility or computer-based information system. Access control is, in reality, perhaps the most common, everyday phenomenon. For example, a lock over a car door is basically a sort of access control. The PIN with a bank's ATM method is another way of access control. Even nightclub bouncers, waiting in front of the door, are another instance of (perhaps) a more primitive mode of access control. Using an access control mechanism is important when persons seek to secure confidential, important, or sensitive information and equipment.
Blue whales, the biggest creatures in the history of the planet, are sustained by tiny krill. Perhaps the Earth's bottomless appetite for classic fuels can be satiated by something even smaller. Algae tend to be more than simply the scum on top of water-feature. When properly utilized, algae can produce fuels, chemicals and materials which are better and cleaner than petroleum-based ones.
